Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491516, here are decompositions:

13 + 491503 = 491516
19 + 491497 = 491516
139 + 491377 = 491516
163 + 491353 = 491516
349 + 491167 = 491516
367 + 491149 = 491516
379 + 491137 = 491516
433 + 491083 = 491516

Showing the first eight; more decompositions exist.
